Abstract

Bentonite chronostratigraphy indicates that deposition of the Viking Formation in central and south-central Alberta and SW Saskatchewan occurred within three chrono-intervals, informally designated Basal, Lower and Upper. Sandstone of the Basal and Lower Viking, times were deposited offshore, while most Upper Viking sands formed along the strandline. In general, these Viking sands trend NW-SE, are multiple, parallel, discrete units surrounded by swales, and are of varying thicknesses.
